marshling Posted October 29, 2006 Report Share Posted October 29, 2006 Hi, I was wondering if there have been any problems with fitting aftermarket 18" alloys ot the is250 Prestige. I am thinking about placing the AMG Style V on my new lexus. Quote Link to comment Share on other sites More sharing options...
dafidav Posted March 5, 2007 Report Share Posted March 5, 2007 remember to stay as close as possible to manufacture specs, especially offset to minimize chance of rubbing when turning on the front tyres Quote Link to comment Share on other sites More sharing options...
ldc Posted March 13, 2007 Report Share Posted March 13, 2007 What is the actual offset of the sports oem 18"? Quote Link to comment Share on other sites More sharing options...

ldc Posted March 23, 2007 Report Share Posted March 23, 2007 I forget whether the larger the offet the more it sticks outward or inwards but i would think rubbing the guards would highly depend on the offset. By the way the placards has the 18s with 8.0" wide both F & R. Quote Link to comment Share on other sites More sharing options...
ant Posted May 13, 2008 Report Share Posted May 13, 2008 this is super old school topic but im on a roll and am fairly up on offsets at least with my S13 silvia! and also been doing hours of reading on amercan lexus forums for offset insights (mostly on GS300s though...) the lower the number on the offset, the further out the wheels will protrude from the hub/wheel arch. You dont have to necessarily stay the same as factory specs, otherwise its hardly an upgrade because its simply cosmetic. The combination of width and offset are the main things to consider. if you are going wider, then the wheel will stick out Both sides of the hub e.g. go from 8" rim to 9" rim, you will have an extra 1/2" (12.5mm) either side of the hub. If you keep the exact same factory offset, your wheel will stick out 12.5mm more toward the edge of the guard, and will stick inward 12.5mm closer to the suspension. it may be that it will hit the suspension, therefore lowering the offset will bring the wheel outwards and allow it to clear the suspension, but the lower ofset will bring the whole wheel edge out more still, so you have to find the right balance. this is a good website for working out where things will sit, but it isnt exact because how low your car is, what size tyres you run and how much camber/caster/toe you run will all effect the fitment quite a lot: www.1010tires.com/WheelOffsetCalculator.asp Quote Link to comment Share on other sites More sharing options...
